Review: I have an Australian shepherd and live in dense woodland! I put this on my dog and didn’t get much relief after 30 days. I did notice the ticks were smaller and not bloating on her! Decided to give it a chance and gave her a second dose. The second dose did the trick. She is tick free and I appreciate not having ticks on my furniture and on me!!!
Review: Easy to use but did not work for any of dogs.

Really not strong enough. I have tried this several times now and must conclude that it is not a good product. Does not get rid of fleas and ticks on my dogs.
